jsonp

问题 I am writing an app right now that uses jQuery and JSONP to get JSON from 3rd party servers. The main idea behind my app is that it is a Front End with only GUI logic and 3rd party servers can be written by anyone to use the Front End. I have no idea what security issues could arise from this but I definitely see it as a potential issue. What are some steps I can take to make sure that a 3rd party server doesn't completely crash my site that will be running the GUI? 回答1: JSONP means that you

问题 I have some local html/js files with which I'd like to invoke some remote servers via https and eventually use Basic Authentication for the request. I am encountering two problems. First is that if I don't specify 'jsonp' for the dataType, jQuery.ajax() request returns the error: Access to restricted URI denied code: 1012 Are my requests considered cross-domain because my main work file is stored locally, but retrieving data from a server elsewhere? So fine, I update the call so it now looks

问题 Can we use jsonp to overcome same domain policy of JS. I need to run script from a domain x to run on domain y. So is it possible to send a script and execute ?? 回答1: Yes, that is the entire point of JSONP. There is no restriction on where you can load a script from (other then the usual http/https conflicts). 回答2: You can import a JS/CSS file from any other domain. If you need to GET data from some other domain, you will need to get it through JSONP. Please note that cross domain requests

问题 Short question: is there a way to make a jsonp request to a server, capture the request, but not parse it as javascript? I am using dataType: "jsonp text" in jQuery 1.5 but it is not working. I'm trying access a cross-domain URL via AJAX with jsonp. The problem is that the other domain (a directory listing at my university) is very old and I doubt the server supports jsonp. In Firefox, I get a "XML tag name mismatch (expected META)" error. In chrome I get a "Uncaught SyntaxError Unexpected

问题 How can i SEND complex type object with array inside it using JSONP var product= {categories:[ {id:1,text:"cat 1"},{id:2,text:"cat 2"}],id:43,price:3535}; $.getJSON(url ,product, function (data) { //i can get the data from the server but i cant pass the complex array to the server }); and on asp.net mvc server: public JsonpResult Create(Product product) { string thisisok = product.id; string needthis = product.categories[0].text; return new JsonpResult { Data = true }; } how should i pass the

问题 Here's the code that I've been trying to work with: $.getJSON("http://api.remix.bestbuy.com/v1/products(search=" + escape(searchCriteria) + ")?apiKey=" + hhApiKey + "&format=json&callback=?", function(data) { if(data.error) { alert("I'm sorry, there was an error processing your request."); } else { alert(data); } }); However, the data that comes back has an error because it doesn't understand the requested URL. I looked at the net tab in Firebug and here's the URL it's trying to call out to:

问题 If I have data in json like this : {"items":[{"id":"2049","channel_code":"HBD","channel_name":"HBO HD"}]} And if you search my data to the server could not find results like this : {"items":[]} Of output as above, how do I read that my data does not exist or is empty? I have written some code that I got but have not found the results I want. This code : var data = { Name: "John Doe", Age: 25, Address: null, CityState: "Denver, CO" }; for (member in data) { if (data[member] != null) //Do

问题 I have a jsonp ajax call which got executed and returns the data to my main function. This is done in the success function by calling that.mainfunction(newData); That means that the main function is called the second time and I think that I'm running therfore in a time/execution problem. While running in the first iteration newData is empty and gets returned empty to the main function. The main function by this framework I must use. So another control is trying to invoke the getter which is

问题 Referring to my question above, the reason I want to retrieve the file is that I want to know how it is structured so I can make the script that I copied work using my data instead. Currently, the $.getJSON url includes the string "callback=?" in it. So is there anyway, I can peek through or see how the data is structured in the file thats inside the $.getJSON url string? actually, Im following along a demo below https://code.google.com/r/kgraham-flr-map/source/browse/examples/medicare
